How about an option that lets you set a maximum amount of participants for which logs are saved. say you set the number at 4, conversations with 5 or more people are automatically set not to be logged.
why do i think this would be a good addition? cause my logs are often filled with useless nonsense from group conversations started by bored people and i know i'll forget to turn the log off each time. if it's too much work, forget it, but this doesn't seem like it'll be much work at all

Sounds like a great idea to me!... I know sometimes I have group conversations that really have no meaning at all so the logging is pointless...

I think Patchou could do it! haha... Please Patchou!

hm yes yes. a very great Idea
i hope patchou can make it

you are right and that's already built in Messenger Plus! Live (not as an option though). Separate chat logs aren't generated above 3 contacts in a chat to avoid unnecessary duplication.
